The previous volume (Number 2) of the UniGRCBS Borders in Perspective Thematic Issue focused on cross-border commuters in Luxembourg and Switzerland (Pigeron-Piroth and Wille, 2019). It dealt with employment, daily life and perceptions of the cross-border commuters in order to point out similarities but also differences between these two countries employing many cross-border commuters. The object of the current Thematic Issue is not to focus on the individuals (the cross-border commuters) but on the organization of the cross-border labor markets. We move from a micro perspective to a macro perspective in order to underline the diversity of the crossborder labor markets (at the French borders, for example) and shed light on the many aspects that impact cross-border supply or demand.
